Title:
Apparently ipv6-related crash in Linux version 3.13.0-43-generic
(buildd@tipua) (gcc version 4.8.2 (Ubuntu 4.8.2-19ubuntu 1) )
#72-Ubuntu SMP Mon Dec 8 19:35:06 UTC 2014 (Ubuntu
3.13.0-43.72-generic 3.13.11.11)
Status in linux package in Ubuntu:
Confirmed
Bug description:
I'm on OFTC and Freenode as Snow-Man if folks want to chat further or
if there's anything I can run with 'crash' to provide additional
information.
This is a KVM guest running under a physical box which is running the
same kernel (43.72)
I've downgraded the KVM guest to Linux tamriel 3.13.0-40-generic
#69-Ubuntu SMP Thu Nov 13 17:53:56 UTC 2014 x86_64 x86_64 x86_64
GNU/Linux; hopefully this will be stable but I'll report back if it's
not. Other guests are running the 43.72 kernel and have not crashed,
but most are single-cpu while the guest which is crashing is 4-cpu.
I have crash installed and a dump file. Here is the dmesg output from
the crash:
